Hi,
</p>
<p>
I experience problems when only one node is up:<br />
Only a few writes to the filesystem put the iowait up to 99% and the volume (lvm) becomes unresponsive.
</p>
<p>
I've had the same problem when status is WFConnection and Standalone, this really defeats the purpose of replicating between two nodes if both of them need to be online, I think I am doing something wrong ?
</p>
<p>
my system:<br />
Linux stan 2.6.22-gentoo-r1 #1 SMP PREEMPT Fri Jul 13 21:06:48 CEST 2007 i686 Intel(R) Xeon(TM) CPU 3.06GHz GenuineIntel GNU/Linux<br />
</p>
<p>
drbd version: Version: 8.0.5 (api:86)
</p>
<p>
LVM version:     2.02.09 (2006-08-17)<br />
Library version: 1.02.19 (2007-04-27)<br />
Driver version:  4.11.0
</p>
<p>
My config:
</p>
<p>
resource mirror0 {<br />
  protocol A;<br />
  # tried protocol C and B as well normally used C but thought<br />
  # perhaps this would help<br />
  startup {<br />
  }<br />
  disk {<br />
    on-io-error   detach;<br />
    # tried pass_on as well<br />
  }<br />
  net {<br />
  }<br />
  syncer {<br />
    rate 100M;<br />
    al-extents 257;<br />
  }<br />
  on stan {<br />
    device     /dev/drbd0;<br />
    disk       /dev/vg0/lv1;<br />
    address    192.168.1.101:7788;<br />
    meta-disk  internal;<br />
  }<br />
  on game01 {<br />
    device    /dev/drbd0;<br />
    disk      /dev/vg0/lv1;<br />
    address   192.168.1.102:7788;<br />
    meta-disk internal;<br />
  }<br />
}<br />
<br />
This problem first became apparent when trying to setup an volume in stand-alone mode as the other node could not be rebooted atm I figured I could configure one node and get the other one involved at an appropriate time, further testing showed the problem with the existing mirror as well (seems logical).
</p>
<p>
Sure hope I can resolve this issue as this only causes problems instead of preventing them.
</p>
